While experimenting with Xfce 4.6 desktop panel's slideshow feature the fan suddenly went loud and hot, and under System Monitor I can see xfdesktop-settings running over 98% CPU Load along with multiple instances of xfdesktop-settings running the same time. After this, not only does this re-occur but I have a blank desktop screen -- not even with drive or folder icons -- and the desktop control panel no longer activates either by right-click or from the Settings customize desktop panel either. Despite reboot doing different sessions the situation is the same. I'm assuming it's because xfdesktop is running multiple and wild somehow from my start-up config but I stripped that down and it still occurs.
